Gusts of up to 80mph in some exposed coastal areas could affect power supplies and cause damage to buildings and trees thanks to a potentially vigorous low-pressure system, the Met Office said. The forecaster issued a yellow weather warning for wind for tomorrow covering much of southern England and Wales, including Cambridgeshire, Norfolk, and Suffolk. It warns of spells of wet and windy weather which will affect many areas later this week and over the weekend, with surface water issues an additional hazard in south-western parts of both England and Wales. Dan Holley, of Norwich-based forecaster Weatherquest, said there is still some uncertainty of how much the stormy conditions could affect the region. There is a rapidly moving area of low pressure which is to appear from the Atlantic on Friday but we are not certain of the track of it and it is quite small so will only affect a small portion of the United Kingdom, he added. The heavy rain will stay to the west of East Anglia but there could be some strong winds in the region from Friday evening. It could cause some disruption but there is still the uncertainty of where it will cover and how deep the low pressure will be. Mr Holley added that the region could see wind speeds of 45mph and if the area of low pressure does hit exposed and coastal areas they could reach 55mph. The Met Office warning, which is in place from 6am until 11.59pm tomorrow, also states that if such winds were to happen there could be damage to trees and perhaps to buildings, possible disruption to power supplies, as well as delayed travel. RAC Traffic Watch spokesman Rod Dennis said: Anyone travelling a serious distance in south-west England and driving on more exposed routes should expect strong, gusty winds on Friday. Reduce your speed, be extra vigilant of other road users and be particularly careful when overtaking high-sided vehicles, as you can be buffeted off course. He also urged motorists not to drive through pools of water. You are risking expensive damage, and putting yourself and passengers at risk, if you drive into water that is of an unknown depth.
